Subject[PATCH] Input: elantech - add LEN2146 to SMBus blacklist for ThinkPad L13 Gen2
Date
ThinkPad L13 Gen2 has both touchpad and trackpoint.
PNP: LEN2146 PNP0f13
With the default protocol (elantech-smbus) trackpoint is not operating,
while touchpad does. Changing to elantech renders both operational.
